Remember Psalm 110?
"The Lord says to my Lord:
'Sit at My right hand,
Until I make Thine enemies a footstool for Thy feet.'
The Lord will stretch forth Thy strong scepter from Zion, saying,
'Rule in the midst of Thine enemies.
Thy people will volunteer freely in the day of Thy power (or army).'"
"Blessed be the Lord, my rock,
Who teaches my hands to war,
And my fingers to fight..."
"He trains my hands for battle,
So that my arms can bend a bow of bronze."
"For though we walk in the flesh we do not war according to the flesh, for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses."
2 Corinthians 10:3, 4
And Handbook 2 gives us a war song for our generation. And notice it is a new song.
"Sing to the Lord a new song,
Sing His praise to the ends of the earth!
The Lord will go forth like a warrior,
He will arouse His zeal like a man of war.
He will utter a shout, yes, He will raise a war cry.
He will prevail against His enemies."
Isaiah 42:10, 13
How will He prevail against His enemies?
"Praise the Lord!
Sing to the Lord a new song.
And His praise in the congregation of the godly ones.
Let Israel be glad in his Maker;
Let the sons of Zion rejoice in their King.
Let the godly ones exult in glory;
Let them sing for joy on their beds.
Let the high praises be in their mouth,
And a two-edged sword in their hand,
To execute vengeance on the nations,
And punishment on the peoples;
To bind their kings with chains,
And their nobles with fetters of iron;
To execute on them the judgment written;
This is an honor for all His godly ones.
Praise the Lord."
Psalm 149:1, 2, 5-9
